letrozole not working for gyno

well got screwed with gyno, anyway was fixing it with erase and that made the gyno come on and off, but i herd letro was much stronger and effective, well i have been on letro for 3 days now @ 2.5 mgs ED, gyno got worse!, so now im going to stack 3 erase and 2.5mgs of letro ED, any thought as to why letro isnt working i dought its buck (from puritysol)
